Shortcut script to connect to servers via SSH without remembering IPs

gistfile1.rb

#!/usr/bin/env ruby

# Connect
#
# Connects to a server by name and user
# Usage: Run `connect <hostname> <user>`
#   <user> is optional and defaults to '<REPLACE WITH YOUR OWN DEFAULT>'

if ARGV[0].nil?
  puts <<-END
Please specify a hostname. USAGE:
connect <host> <username> - Username is optional
  END
  exit 1
end

host = ARGV[0].to_sym
user = ARGV[1].nil? ? 'user' : ARGV[1] # REPLACE 'user' with your preferred default username

hosts = {
  pluto: '123.45.6.78',
  minnie: '345.667.8.9'
  # Add as many hosts as you'd like here
}

puts "Connecting #{user} to #{hosts[host]}..."

system("ssh #{user}@#{hosts[host]}")

Edit the default user variable and change the hosts hash to match your servers. Place somewhere on your system, make it executable with chmod +x scriptname and run it whenever you need to connect to one of your servers like connect pluto. No more remembering IP addresses.
